People living in low-lying areas in river valleys from north of Coffs Harbour to the Nambucca are being warned of the chance of flash-flooding overnight.
The Weather Bureau has issued a flood watch for minor flooding in the Orara river west of Coffs Harbour, for Coffs Creek and the Nambucca river, tonight and tomorrow morning.
There is a warning for possible moderate flooding in the Bellinger river.
The Bureau says there is a 75 per cent chance of flash flooding linked to locally heavy rainfall and possible severe thunderstorms.
Flash flooding saw the SES called out to sand bag low lying properties in the Forster-Tuncurry area early this morning and repair leaking roofs around Port Macquarie where over 100 millimetres of rain was recorded.
